6 Claims.

The object of this invention is to devise a novel device for applyinglacquer, nail polish or other liquid material, and, while primarilydesigned for applying such material to nails, it is not limited to suchuse and can be employed for many other purposes.

A further object of the invention is to provide novel means forcounterbalancing a brush so that, when the brush carrying end of thecontainer is directed upwardly, the brush will be automaticallyretracted to be positioned in the delivery passage from the containerfor the material being dispensed.

A further object is to provide for limiting the outward travel of thebrush, and for this purpose the rod which carries the brush is providedwith a stop, which in some cases may be in the form of a valve tocooperate with a seat at the entrance end to the delivery passage. Inthis manner, the amount of material passing to the brush is metered. p

The counterbalance acts as a piston to effect the feed of the materialto the brush and also as an agitator to maintain the liquid in ahomogeneous condition.

With the foregoing and other objects in view as will hereinafter clearlyappear, my invention comprehends a novel device for applying liquidmaterial.

It further comprehends a novel construction and arrangement of acontainer and of a brush carrier having `a counterbalance or weight toretract the brush within the delivery passage of the container and alsowith means to limit the outward movement of the brush and if desired tocontrol the amount of liquid fed -to the brush.

For the purpose of illustrating the invention, I have s-hown in theaccompanying drawings preferred embodiments of it which I have i'ound inpractice to give satisfactory and reliable results. It is, however, tobe understood that the various instrumentalities of which the inventionconsists can be variously arranged and organized and the invention isnot limited to the exact arrangement and organization of theseinstrumentalities herein set forth.

Figure 1 is a perspective view of a device for applying liquid,embodying my invention.

Figure 2 is an exploded view of the component parts.

Figure 3 is a sectional elevation.

Figure 4 is a sectional view of a portion of the device in an invertedposition.

Figure 5 is a sectional view of another embodiment of the invention.

Similar numerals of reference indicate corresponding parts.

Referring to -the drawings:

A tubular casing l has one end closed and the other 'end open and inFigures 1 to 4 inclusive the casing or container is sectional, beingprovided with a tip 2 connected with the body of the casing in anydesired manner and as shown by a friction fit. IThe tip 2 at its innerend has a chamber 3 leading from thechamber of the casing andterminating in tapered walls forming a stop or seat 4 at the entranceend of a dispensing or delivery passage 5. The outer wall of the tip hasa threaded portion 6 and preferably tapers forwardly towards its freeend.

A brush l is secured in any desired or conventional manner to the outerend of a rod 8 which latter has secured to its inner end a weight orcounterbalance 9 which is detachable since it is shown as in 'threadedengagement with the rod. Selectively positioned on the rod is a stop orseal l0 which may serve as a valve and controls thev amount of liquidpassing to the brush. The counte'rbalance acts as a piston to feed theliquid to the delivery passage, and for different vlscositles of liquida heavier or lighter counterbalance can be employed to control the flowin accordance with the character of the liquid which is being used.Thestop limits the outward movement of the brush so that only a desiredamount of bristles are exposed.

A cap Il has a threaded portion l2 to engage the threaded portion 6 ofthe tip and when in closed position on the tip seals the outer end ofthe delivery passage 5.

The casing can be reillled with liquid on removal of the tip.

In the embodiment seen in Figure 5, the casing and tip are integral, anda closure i3 is detachably connected with the inner end of the casing.Otherwise the construction and arrangement of the component parts arethe same as that already described in connection with Figures 1 to 4,inclusive.

The operation will now be readily apparent to those skilled in this artand is as follows:

The counterbalance has a clearance with the inner walls of the casing tolimit the amount of pumping action, and since the casing has been shownas round the counterbalance has been shown as square. The rod has therequisite clearance in the delivery passage so that when the device isinverted the brush will be moved forwardly to be presented exterior ofthe front end of the top of the casing and a proper amount of liquidwill tlow through the passage to the brush. The liquid dispensed canthus be applied to a desired surface without spilling or dripping.

When the brush end of the casing is directed upwardly, thecounterbalance will automatically move inwardly carrying with it thebrush and the stop or seal and the brush will be retracted into thedelivery passage.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. In a device for applying liquid, a tubular casing closed at one end,having an internal chamber and having a tip with a discharge passageleading from the chamber, a rod Within the chamber, a brush at the outerend of the rod and within the passage when the casing is in an uprightposition with the tip directed upwardly, a weight within the casing andcarried by the rod to move it and thereby the brush, said weight beingfree to move in either direction by gravity, whereby liquid is fed fromthe chamber to the passage and the brush is moved outwardly of thepassage when the casing is inverted from an upright position, and themovement of the weight when the casing is returned to an uprightposition retracting the brush within the discharge passage.v

2, The construction deiined in claim 1, wherein the Weight is at theinner end of the rod, and a stop on the rod limits its outward movement.

3. In a device for applying liquid, a tubular casing closed at one end,having an internal chamber and having a tip with a discharge passageleading from the chamber to the discharge passage, a rod within thechamber and extending into the discharge passage with a clearance topermit liquid to pass around the rod, a brush at the outer end of therod and within the passage when the casing is in an upright positionwith the tip directed upwardly, a weight carried by the rod to move itand thereby the brush, said weight being free to move in eitherdirection by gravity, whereby liquid is fed from the chamber to thepassage and the brush is moved outwardly of the passage when the casingis inverted from an upright position, and the movement of the weightwhen the casing is returned to an upright position retracting the brushwith in the passage.

4. The construction deiined in claim 3, wherein the weight has aclearance with the inner wal-l of the chamber to permit liquid to bypassthe weight.

5. yIn a device for applying liquid, a casing for liquid having adischarge passage, a brush normally within said passage to substantiallyclose it when the casing is in an upright position with the dischargepassage directed upwardly, a weight connected with the brush and free tomove by gravity in opposite directions and of sufficient mass to retractthe brush within the passage and to move itoutwardly of the passage, thetilting of the casing towards an inverted position causing the gravitymovement of the weight tomove the brush outwardly oi the pasv sage andthe return of the casing to an upright position retracting the brushwithin the passage.

6. In a device for applying liquid, a casing for liquid closed at oneend, having an internal chamber and a discharge passage leading fromsaid chamber, the inlet to said passage forming a seat, a rod withinsaid chamber, a stop on the rod to engage the seat` and` seal saidinlect, a brush connected with the outer end of said rod and normallywithin said passage when the casing is in an upright position with thepassage directed upwardly, a weight connected with the rod and free tomove by gravity in opposite directions to retract the brush within thepassage or .move it outwardly thereof, the tilting of the casing towardsan inverted position causing the gravity movement of the weight to movethe brush outwardly of the passage and the return of the casingto anupright position causing a gravity movement of the weight to retract thebrush within the casing.
